Improvement of performance and flexibility for photovoltaic module using individual DC/DC converter
ABSTRACT This paper focuses on the improvement of performance for PV generators in nonideal conditions and proposes topologies to minimize the degradation of performance caused by these conditions. It also presents a flexible PV module concept which consists of paralleling DC/DC converters with maximum power tracking (MPPT) and power balance functions. Optimum power configuration and balance of the paralleling modules system are developed in this paper. And the output voltage and MPPT of DC/DC converter in this PV module are by means of a suitable phase shift modulation. The prototype photovoltaic modules design is exploited. Some design considerations and issues on performance of the system are discussed. Experimental results are reported in order to demonstrate the suitability of the proposed methods in the application.
